9. Output Devices - Collin and Alana¶
This is the group documentation for Alana Duffy & Collin Kanofsky
The assignment for this week was to measure the power consumption of an output device.
Voltage and Current Used¶
The voltage usage varied as the servo turned until it hit a low or high point and turned around.
We also had to measure current, the current I got was around 0.12 Amps and it did fluctuate a bit. We got some advise from richard shan in getting this value.
How much power was Used¶
To calculate the power we used the formula P=VI
-
P is power
-
V is voltage
-
I is current
The current value we got was ~0.12 Amps and we used a 3.3 volt power supply. Plugging the values into the equation we got:
P=(3.3)(0.12)= 0.396 watts
This was a fairly expectable value as group A got 0.5W at their value. Because we used a servo, a moving component, it’s likely that it would a decent amount of power.
